A digital hard drive is a type of non-volatile memory that stores digital data encoded on magnetic platters. It was introduced in 1956 for storing data in an IBM accounting computer. Currently, applications for hard disks have exceeded computer borders and they are included in a suite of digital devices (DVD players, MP3 players and even mobile phones or PDA).
The need for more secure methods of data storage resulted in the development of more complex configurations such as RAID arrays, NAS systems (Network Attached Storage) or SAN systems (Storage Area Network). The configurations can provide efficient and stable access to large amounts of data.
The digital hard drive is one of the most important computer components because in its absence a computer can not be used. Why can't a computer be used? For the fact that on the HDD surface is stored all the data you work with your computer and the computer will start only if the BIOS checks for the hard drive. If BIOS will not find the digital hard drive it will signal an error.
There are several rules that must be followed when installing a digital hard drive on a computer. A tip would be that you do not fix the HDD in position with screws until you set it up and run your computer at least once. This is because there could be some conflicts and you must change the ribbon.
First, you install only one IDE drive, which must be set to "Master." If you have two IDE disks you must decide which one will be set to "Slave" and which one to "Master." If you have a hard drive digital 3.5" and want to install it in a space for a 5.25" hard drive you will have to install two rails on the hard drive to fit in the 5.25" space. Most HDD are purchased with these rails.
To connect the HDD connect the 20-pin ribbon in the first IDE channel on the motherboard by attaching the red ribbon wire to the first pin. Connect the other end of the ribbon to the hard drive digital. If you do not have a knotted ribbon, enter the ribbon with the red wire on the right. Connect the HDD LED to the motherboard. Connect the power wire to the red wire on the left.
The power wire can be inserted only in one way due to its shape. Turn on the computer. If the hard drive digital is not detected or the computer will not start, you need to see if the drive produces noise. If you hear noise, check the jumpers or the connections. If you do not hear any noise and the computer started, enter BIOS to configure the drive or set it to "Autodetect."
Check if the IDE port is enabled. If all goes well, after the computer starts and detects the hard drive digital, you will see an error message such as ‘’System disk not found’’ or ‘’Please insert system disk.’’ Everything is fine and you can use your computer.
